United States Patent() 2,743,863 Patented May 1, 1956 to 9, inclusive,the case or box shown herein is formed of fiberboard, cardboard,laminated material or other appropriate composition material and has twoside walls 10 and 11. Along the top edge of wall 10 there is a fold line12, defining the hinge line of a cover ap 13 attached to the top edgeand being 'one-half as wide as the case or'box.

Along the top edge of wall 11 there is a fold line 12, defining thehinge line of a complementary cover ap 13' attached to the top edge andalso being one-half as wide as the case or box. rl`he two side walls ofthe case are connected by two end walls 14 and 15. Along the top edge ofeach end wall there is a Hap 16, the flaps 16 cooperating with the aps13 and 13a to close the box flush with the end of side wallill when theblank is folded tothe position of Fig. 2, this liap being secured 'toside to the bottom edge and being as wide as the case.

wall 11 by means of staples 11a.

Along the bottom edge of wall 1) there is a fold line 27, defining thehinge line of a bottom flap 28 attached This llap is provided with acentral, longitudinal fold line 29 ....bottom edge and also being aswide as the case. yflap is provided with a central, longitudinal foldline 32.

for a purpose which will hereinafter become clear. the bottom edge ofwall 11 there is a fold line 39, defining the hinge line of a secondbottom flap 31 attached to the This Along the bottom edge of eachendwall there is a liap 33 extending one-half the length of the case,substantially as illustrated.

l Each Iiap 33 is divided in half by a central longitudinalv "opening 34extending from each end wall to the end of each ap. After securing theflap 15b to the end of side wall 11 by means of staples 11a, and withthe end walls 14 and 15 p and the side walls 1i) and 11 disposed atright langles yto each other, the flaps 33 are folded upwardly toprovide. a floor for the case. rIfhe flaps 31 and 28 are each thenfolded at right angles to themselves along fold lines 32 and 29,respectively, whereupon the outer portions of the thus folded flaps areinserted upwardly through the openings 34, as shown in Fig. 2,completing the bottom closure and at the same time dividing the bottoniof the Case into longitudinal halves.

The flaps 33 are provided with fold lines 35 for a purpose to behereinafter referred to. For use as an egg case or other purpose, thereis a transverse partition 17, with reversely turned or folded sideportions 1S that extend from the top of the partition as viewed in Figs.l and 3 to a point midway its ends. At this point, the partition isprovided with a score line 19 whereby the portion 29 of the partitionbelow the score line may be folded upwardly around the score or hingeline to a horizontal position, at right angles to the partition, asshown in Figs. l and 3. The bent horizontal portion 24B constitutes abrace for the side walls 10 and 11 thereby preventing the collapse ofsaid walls. The folded side portions l5 of the partition are glued orotherwise secured to the side walls. The partition is centrally locatedso as to divide the case into two compartments, and to furnish a rigidreinforcement centrally of the case. The flaps 13 and 13a are adapted tofold inwardly over the top edge of the partition 17.

The end walls 14 and 15 are formed with cutout openings 24 which formhand hold openings for transporting the case from place to place.

In using the case for shipping eggs, each compartment Along v willcontain a stack of conventional fillers and flats (not shown) forholding the individual eggs. The horizontal bracing portion 20 of thepartition 17 will rest on one of said devices and be supported thereby.Such devices with the partition 17 and bracing portion 20 will assist inthe general bracing of the case from end to end and from side to side.

As shown in Fig. 9, the aps 33 may then be folded upwardly along foldlines 3S on both sides of flaps 28 and 31, dividing the caselongitudinally and providing lateral reinforcement intermediate sidewalls 19 and 11 and flaps 28 and 31. It will also be noted that the endof the left hand flap 33 when so bent will support the outer end ofportion 20 of partition 17, as shown in Fig. 9, providing a shelf-likestructure. It will also be noted that upward bending of portion 2b islimited by abutment with the bottom edge of one side portion 18, asshown in Fig. 2. Thus the aps 33, 2S and 3l also divide the interior ofthe case into individual compartments which may receive fillers and ats.

It will be understood that the edges of the walls of the case engage theunderside of the cover flaps and thus give good support thereto.Additionally, the top edge of the partition 17 gives further supporttransversely to the center of the top flaps 13 and 13a.

In order to collapse the the case, the top and bottom flaps 13, 13a, 16,28, 31 and 33 are opened outwardly and the horizontal bracing portion 29of the partition 17 is pressed downwardly into a prolongation of thepartition as shown in Fig. 8. The walls of the case are then pressedtowardv each other and because of the reverse folds 18 of the partition17, all folds or angles open outwardly and the case may be folded downsubstantially flat without tending to break or stretch the iberboard atany corner fold.

The flaps 33 may be folded upwardly to lie flush with the inner sides ofend walls 14 and 15 before pressing the side walls together, making amore compact unit. The flaps 28 and 31 may then be folded upwardlyagainst the side Walls and 11 providing an extremely compact unit forshipping.

The case is readily and quickly set up by opening the walls of the caseand pressing the portion of the partition to horizontal position betweenthe side walls.

In the modified form of partition 17 shown in Figs. l0 and 11, theportion 29 thereof below the score line is formed with folded sideportions on both of its side edges. When the portion 20 is folded tohorizontal position, the side folds 25 thereof loosely but frietionallyengage the side walls 10 and 11 of the case thereby affording additionalrigidity to the case.

In all other respects, the form of partition shown in Figs. l0 and ll issimilar to the form of partition shown in Figs. 2 to 9 and similarreference numerals are used to indicate similar parts.

Fig. l2 illustrates a further modified form of partition 17" similar inconstruction to the form of partition of Figs. 2 to 9, but provided witha finger opening 26 in the bendable lower portion 20" to facilitatemanipulation of the lower portion.

It will be seen that I have provided a strong, serviceable egg case orcarton, with a cover and bottom that can be turned back, which case canbe easily set up or folded.

While I have illustrated and described preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modications coming within the scope of the invention asdefined in the appended claim.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent A shipping case for eggs and thelike having side and end walls and a bottom closure, a verticallydisposed Z- shaped partition between the side walls and hingedlyconnected thereto, an integral horizontally disposed bracing member forthe side walls hingedly connected to the partition, said bottom closurecomprising end aps integrally connected to the bottom edges of said endwalls and foldable upward, each of said end aps extending substantiallyone half the length of the case and having a central, longitudinalopening dividing said flaps into two substantially equal halves, andside aps integrally connected to the bottom edges of said side walls andfoldable upward, each of said side flaps extending substantially thewidth of the case and having a central longitudinal fold line wherebythe outer portions of said side flaps may be folded upwardly into thecase through said openings in said end flaps andbrought intojuxtaposition with each other, said end aps having transverse fold linespermitting the same to be folded upwardly on each side of saidjuxtaposed outer portions of said side aps whereby to reinforce saidcase intermediate said side walls and said juxtaposed outer portions ofsaid side flaps and to divide Lne bottom of the case into partitions,one of said end aps at the end thereof abutting the end of said bracingmem' ber when said flap is folded upwardly along said transverse foldlines.
